Fax Architecture Seamlessly Blends PSTN and IP Real-Time Fax
For years, Commetrex has been the leading developer of fax-related technologies for the carrier-
equipment industry. Our TerminatingT38 product remains an industry exclusive, and serves as
the reference standard for the T.38 Interop Lab. PowerRelay for T.38 is a critical component in
the media gateways of many of the major manufacturers and access-silicon vendors. And our fax
modems have been an industry staple for 10 years. But as you might have picked up if you've
read a few issues of The Commetrex Outlook, we've been busy bringing Open
Telecommunications Framework Ò Kernel, the OpenMedia(tm) streams framework, and their all-
IP SIP- and host-based integration, BladeWare(tm), to market. Moreover, in the last few months
we've begun to ship the MSP-H8 and MSP-320 PCI boards, which support voice and our veteran
fax technologies.
Now, we've bundled this massive technology and product portfolio into a new architecture for the
fax industry that enables OEMs and system developers to support any fax application on any
network, using any protocol, through any gateway, and do so transparent to the application. Click

IP Unity, First to Market MMTF(tm)
What does it take to add fax support into a unified messaging platform? IP Unity recently found
out. Their service-provider customers are asking them to add fax support to the Harmony6000
Media Server. So, IP Unity is adding T.38 and G.711 pass-through terminating fax to the product,
and chose Commetrex as the vendor to supply it, an easy selection since Commetrex' Multi-
Modal Terminating Fax (MMTF) is the only product on the market that can do the job. With
MMTF, Harmony6000 can terminate real-time IP faxes from any gateway, even if it does not
support T.38.
IP Unity is a developer of enhanced service platforms and applications that enable telecom
service providers to develop, manage, and deploy services that seamlessly integrate voice, data,
fax, and video applications into one communication interface.
Commetrex' PortableT30T (P30) implements the protocol that terminates a fax. The Fax Modem
Bundle provides analog fax modems. PowerRelayT for T.38 implements the ITU
recommendation for real-time IP fax. And TerminatingT38T combines P30 and PowerRelay to
support real-time terminating fax on IP media servers. Multi-Modal Terminating Fax (MMTF) is
an integration of all of these major system components to create a system that allows a media
server to terminate faxes from PSTN-IP gateways supporting either T.38 or G.711 pass-through
for fax transmissions.
"We are grateful that Commetrex was there to provide us with the support and the product we
needed at the right time," says Brett Azuma, Senior VP of Marketing for IP Unity. "It was never a
question of whose T.38 we would purchase, just a matter of the sequence of events. The quality
of the product we licensed is good, and it has enabled us to move rapidly to market. We have
customers ready and waiting for the finished product, and we're excited to offer fax support in our
platform."

Commetrex Supports Netergy Customers
Commetrex Corporation and Netergy Microelectronics, Inc., a subsidiary of 8x8, Inc. (NASDAQ:
EGHT), have entered into an agreement whereby Commetrex will provide technical support to
licensees of Netergy's Veracity(tm) Voice and Fax over IP (VoIP, FoIP) embedded software
technology.
Under an existing agreement, Netergy had licensed Commetrex' fax modem and T.38 software
technology and integrated the functions into Netergy's Veracity software suite. In addition to T.39
and G.711 fax pass-through, Veracity provides all of the industry-standard call-control protocols
deployed in VoIP networks today, including H.323v4, SIP, MGCP and Megaco, the G.7XX series
of audio codecs, and related network functions.
Veracity software runs on Netergy's Audacity-T2 and T2U access semiconductor products.
Netergy has licensed the chips and software to Myson Century, Inc.
(http://www.myson.com.tw/),
for which Commetrex is also offering support.
"We are pleased to work with Commetrex to provide existing Netergy customers with access to
technical support resources that can help them to realize their product-development goals,"
stated Bryan R. Martin, 8x8 chairman and CEO.
Commetrex' CEO, Mike Coffee, stated, "Given our focus on providing telecommunications
equipment developers with integrated software solutions, we believe that engaging with Netergy
and the Veracity customers is a natural evolution of our strategy."

G.168 - 2002 Testing Exposed
Our G.168 test results are now on-line at
http://www.commetrex.com/pd/G.168 Testing Forum.nsf/?open.
This is our second-generation line echo canceller (LEC). Our first-generation
product is now widely deployed, but it was a low-resource LEC, not designed to pass G.168. This
next-generation product has been in development for 18 months, and the results of our testing
are excellent. In fact, they are so good we decided to put them on-line to easily answer the
question: "What testing have you done?"
It's all there, including the intermediate results with the failures. So, if you're really interested, you
can paw through the changes we went through to achieve conformance.
Interested? It's easiest to view the forum if you click on the "By Category" view. The final tests
are in the category "ITU-T G.168 Tests on Commetrex' LEC". All the other categories are
intermediate results, test set-ups, etc.
If you are interested in our LEC and want to discuss the test results and any other question
regarding the product, call or e-mail Bruce Adams at 770-449-7775
X370/badams@commetrex.com.
Open-Source SIP
BladeWare(tm) supports SIP. When we began the project, we decided to take a look at open-
source SIP projects and found at least five, four of which we evaluated: SIP Express Router
(SER), NIST, Vovida, and oSIP. We selected oSIP, which is sponsored by WellX (Versailles,
France), which happens to be a Commetrex customer (no bearing on the selection, however).
We were looking for software that was in active use with the attendant activity, C-coded, and at
home in both Win32 and Linux development environments. SER lacked Win32 support and an
external API. NIST is coded in Java, which does not integrate well with non-Java code. Vovida
lacks Win32 support and is quite large. On the other hand, oSIP was small, C-coded, portable,
Interop-proven, widely used, and actively supported. It appeared to be a good fit and it was.
Aymeric Moizard, oSIPs primary developer, and the rest of the developers in the oSIP forums are
very supportive.
If you're looking for a good open-source SIP, take a look at oSIP. And if you want to talk to our
lead SIP developer, give Mike Wells (mwells@commetrex.com) a call at 770-449-7775 x 380.
